Justhadathought the problem that the police cause amongst the gangs around me is the relentless targeting of (mainly) young men, particularly black men, from their early teens onwards.
This creates a situation in which a significant group of society simply don't trust the police. With anything, ever, under no circumstances.
So they address what they see as crime against them or their allies through reprisals.
Of course individual's behaviour is their own choice. Although individual police officers work within structures that are racist, sexist, classist and prejudiced to the core, and in which they know they'll be protected to the nth degree if, for example, someone dies within their custody, they're filmed tasering a 61 year old man whose flat the entered forcibly for 'drug related offences' (spoiler, there weren't any), grope a female suspect or witness, knock someone from the travelling community about a bit etc etc etc ad fucking infinitum.
So their actions are their responsibility, although the protection that they're afforded results from their position as police officers, rather than their race, class or sex.
